Broken out from bug 26372:
When typing a namespace prefix (eg 'Project:', 'Help:', 'Talk:') into the search box, the suggestions traditionally return a few items from the beginning of that namespace, alphabetically.
On live Wikimedia sites which are running the Lucene search engine, only a single result is returned. (It can be verified this isn't an issue on the UI side by checking the actual opensearch responses -- they really do only return a single page title.)
For instance, on en.wikipedia.org right now typing "Talk:" returns the single result "Talk:&&". "Help:" returns "Help:A day in the Life", but no others.
More results are expected, especially when the first result is something funky-looking like a series of punctuation. :)
